Title:
THREE-PHASE-INTERLEAVING EXTENDED-RANGE EFFICIENT-ISOLATION BIDIRECTIONAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2024/051317
Kind Code:
A1
Abstract:
Disclosed in the present application is a three-phase-interleaving extended-range efficient-isolation bidirectional converter, comprising a three-phase bridge type switching circuit, a resonant cavity, three transformers and a three-phase bridge type rectifying circuit. The resonant cavity comprises three resonant circuits, and each resonant circuit comprises a first capacitor, a second capacitor, a third capacitor, a first inductor, a second inductor and a third inductor. One end of the first inductor is connected to one end of the second inductor, one end of the first capacitor and one end of the third capacitor, and the other ends of the first inductor and the first capacitor are respectively connected to one end of the third inductor and one end of the second capacitor. Said end of the third inductor is connected to the midpoint of a bridge arm in the three-phase bridge type switching circuit, and the other ends of the second inductor and the third capacitor are respectively connected to the other ends of the third inductor and the second capacitor and are connected to a primary winding of a transformer. In the three resonant circuits, the ends of the second capacitors connected to the first capacitors are connected to each other to form a Y-shaped connection. Secondary windings of the three transformers are respectively connected to the midpoints of the three bridge arms of the three-phase bridge type rectifying circuit.
